CCMT09T304‑FW4 WSM20S turning insert — Tiger·tec Silver, 7° clearance (Walter Tools)

The CCMT09T304‑FW4 WSM20S is a rhombic 80° indexable turning insert engineered for demanding turning in stainless steels and superalloys, offering a robust chipcontrol geometry and a coated carbide grade for improved thermal resistance.

• Tiger·tec Silver coating for heat resistance
• FW4 chipbreaker for secure chip control
• 7° clearance angle for consistent cutting
• Rhombic 80° shape with 0.4 mm corner radius

High‑temperature performance for stainless steels and superalloys

The coated carbide grade WSM20S, part of the Tiger·tec Silver series, is designed for the tribological and thermal challenges of groups M and S (stainless steels and heat‑resistant superalloys). The advanced coating reduces adhesion and supports a stable cutting edge, which helps to avoid built‑up edge and premature flank wear in tough materials. The chipbreaker geometry improves evacuation and reduces the risk of long, stringy chips, translating into fewer interruptions and higher process reliability — an important consideration for batch production and safety‑critical components.

Precision geometry that improves surface quality and tool life

The rhombic 80° shape combined with a 0.4 mm corner radius provides a balance between edge strength and finishing capability: the modest radius gives a robust cutting corner for interrupted cuts while still enabling a fine surface finish on profile turning. A 7° clearance angle helps to maintain a predictable contact geometry and reduces rubbing in heavy cuts, which benefits tool life and reduces heat generation. The FW4 chipbreaker is tuned to support consistent chip segmentation in loaded cutting conditions, making the insert a pragmatic choice where both reproducibility and part quality matter.

Productivity benefits and shopfloor integration

As a production‑oriented grade from Walter Tools, this insert supports repeatable performance and fewer tool changes under demanding conditions, which improves uptime and machining efficiency. Using a coated, application‑focused grade means higher cutting speeds and longer intervals between indexings compared with uncoated carbide in similar tasks. For users aiming to streamline tool inventories, the CCMT geometry and common dimensions simplify stocking and allow rapid replacement in standard toolholders. Selection of cutting data should follow manufacturer guidance and be adapted to the specific alloy and rigidity of the machine setup to unlock the full productivity potential.

FAQ

Which materials is this insert intended for?
The CCMT09T304‑FW4 WSM20S is specified for stainless steels (ISO group M) and heat‑resistant superalloys (ISO group S), the grade and chipbreaker support secure chip formation in these materials.

How does the FW4 chipbreaker affect machining?
The FW4 chipbreaker on this insert promotes controlled chip segmentation and evacuation, reducing chip‑related interruptions when machining high‑temperature alloys with the CCMT09T304‑FW4 WSM20S.

What advantage does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating increases thermal resistance and reduces adhesion, which helps maintain a stable cutting edge and extends tool life under elevated cutting temperatures.

Is the 0.4 mm corner radius suitable for finishing?
A 0.4 mm corner radius offers a compromise between a strong cutting edge and surface finish; it is suitable for many finishing and medium‑duty turning tasks using the CCMT09T304‑FW4 WSM20S.

Can this insert be used in standard CCMT toolholders?
Yes, the CCMT designation matches standard indexable turning toolholders, enabling straightforward integration into existing setups for the CCMT09T304‑FW4 WSM20S.
